Tehran, Iran’s capital, ranks among the world’s fast-growing cities. In the early 1940s, Tehran’s population was about 700,000. By 1966, it had risen to 3 million and by 1986 to 6 million. Today, the metropolitan area has more than 10 million residents. This explosive growth has had environmental and public health consequences, including air, water pollution and the loss of arable land and public realm. The ever increasing land value makes developments and the replacement of urban open space and easy choice. With the disappearance of open public plaza, by traffic islands and motorways the predominant public space left in the city is its many traffic arteries.
With a young population and the Cars as the main mode of transport in the city, the many highways of Tehran come to a grinding halt during rush hour.
